Multi Band Hysteresis Modulation Based Current Control Technique for Seven Level Grid Connected Voltage Source Inverter
نویسنده
چکیده
This paper deals with the multiband hysteresis control technique which tracks the desired reference current and provide desired voltage and current waveform with less distortion for grid connected systems. Cascaded H bridge multilevel inverter is used in high power and medium power applications. Multiband tracks the desired reference current and is used for evaluating the performance of multilevel inverters. This control technique is based on time domain formulation. The efficiency of the controller in reducing total harmonic distortions and switching losses based on the instantaneous switching frequency, system parameters and number of levels is studied. The simulation results are obtained for seven level cascaded H bridge multilevel inverters.
